PlCKER-CHECK FORILOCMS.

SPECIFICATION forming part of Letters Patent No. 382,640, dated May 8. 1888.

' Application filed August 29, 1887. Serial ;No.2-l8, 133. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM DRIVER, of Manville,in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Picker-hecks for Looms, of which the following "is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to picker checks, whichare devices for limiting or checking the throw in one direction of the picker of a loom.

The objects of my invention are to provide a picker-check which will be spring-actuated, and thereby will gradually ease of and check the blow of the picker; and, further, the invention seeks to provide a durable and efficient check which will be much preferable to the 01d form of picker-check straps.

To the aforesaid purposes my invention consists in certain details of construction and arrangement of the several parts of the device, all as hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a side view of a shuttle-box and the upper portion of a picker-stick with its picker, together with my improved picker-check; and Fig. 2 is an under side view of Fig. 1, with the picker omitted. Fig. 3 is a side view of a shuttle-box and a portion of an ordinary overpick picking mechanism, with another form of my improved pickercheck combined therewith. Fig. 4 is a detached detail end View of a portion of the device shown in Fig. 3, and shows the check and its guide and the spindle, which isin crosssection. Fig. 5 is a side view of parts such as those shown in Fig. 3, with a different form of check; and Fig. 6 is a detached detail end view of the check shown in Fig. 5, and which slides on the guiding-spindle, shown in crosssection. In the said drawings like numbers of reference designate corresponding parts throughout.

Referring to the drawings, the number 7 designates the ordinary shuttle-box for the shuttle, and 8 is the picker for driving the shuttle out of the box. The check-rod 9 is mounted in the two bearings or hangers 10, which are attached to the shuttle-box, and this rod is adapted to be reciprooated endwise in such- 12, which slides on the'rod, and may be secured at any adjustment thereon by means of its set screw 13. The inward throw of the rod 9 is limited by means of the enlargement 14, which in Figs.3 and 5 is adjustable, the enlargement striking against the bearing 10, and thereby effecting the limitation.

The outer end of the check-rod 9 in Figs. 1 and 2 is formed with a slot, 15, in which is adjustably mounted, by means of the nut 23, the check 16,which is provided with the rawhide cushion 17, and has one end thereof sliding in the guide 18, which is secured upon the shutt-le-box for steadying the motion of the check.

The construction shown in Figs. 1 and 2 is designed for use with the ordinary pickerstaff, while the two constructions shown in Figs. 3 and 4. and Figs. 5 and 6, respectively, are adapted to be used with what is known as an overpick loom, in which the picker 8 slides to and fro on the guiding-spindle 19, which is fixed over the shuttle-box 7. Both the constructions shown in Figs. 3, 4, 5, and 6 comprise the checks 16, which,'however, are composed of the two members 20 and 21, the former of which is adjustablysecured to the check-rod 9 by means of the set-screw 24, and carries the member 21, against which the picker strikes directly. K p

In Figs. 3.and 4 the member 2l is made quite long, and is fixed upright, so that the reciprocatingcheck-rod can be placed subjacent to the shuttle-box and allow the check to reach the picker. 1 a

In Figs. 5 and 6 the member 21 is provided with a perforation, 22, to receive the guidingspindle 19, and the check-rod is placed near the upper part of the shuttle-box.

The improved check is a very durable one, and relieves the loom of the effects of the continual dead blow of the picker at its outward limit of vibration.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the shuttle-box, of a reciprocating check-rod provided with a check for receiving the blow of the picker,

secured to the check-rod by a clamp to adjust the same and mounted in bearings, a

spring mounted on the check-rod and abutting with one end against one of the said bearings,

5 and astop adjustable by means of a set-screw for engaging the other end of the spring and for regulating the tension of the spring by means of its adjustment, substantially as and for the purpose herein described.

IO 2. The combination, with the shuttle-box 7,

of the spring-actuated reciprocating check-rod mounted in bearings 10, and the check 16, ad-

just-ably mounted on the check-rod by means of the set-screw 24, and comprising the mem- 15 bers 20 and 21, substantially as and for the purpose herein described.
